Cant Join Dungeon and Can't Create a Group

I cant find dungeon because game says ''One or more party members are pending invites or disconnected''.Also, I cant invite a friend to create a group.I already tried to reconnect but I still have this problem.By the way, I'm not in a group. Please help me.Thank you.

Try unstucking. If that doesn't help, I guess just try and wait. If by tomorrow, the problem persists, write a ticket.

i already solved it. I write a ticket but GM wasn't answered. I tried write to chat /script LeaveParty() and it solved.
